PEARL-MHA'OOK, 'GUST E. RASMUSSEN, AND GILBERT W. SKIN'NER, OF SEATTL, WASHINGTON- ATOMIZER.

Application filed February 11, 1924. Serial No. 692,017.

This invention relates to atoinizers. and more partlcularly to means whereby a liquid 'such as oil may be very iinely atomizedlandl` eilectively spread in this atoii'iized condition over an extended surface.

It is the principal object ot' vthe invention to provide a device of the above character that is especially designedvfor use in oiling bread pans, or the like, and which coinprises inits construction ii'ieaus whereby the oil delivered therethrough may not only be atomized, but may be discharged or spread evenly over the entire inner surface loi" the.

ans.

A still further object of the invention is.

to provide an atomizer comprising a cuplike body into which the oil or other liquid to be atoinized, is delivered and also -intoV Which air, under pressure, if; adapted to be delivered to blowv the oil from the cup through an impeller or ian which is to be actuated to atoii'iize and spread the oil, Other objects of the invention reside in the Various details oic construction and conibination ot parts as wvillbe hereinafter described.

In accomplishing the various objects ot the invention, we have provided the iin.- proved details ol' construction the pretei-rcd 3,forms of which are illustrated in the accom` throughfwhichthe discharge end of an aii" valve housing 3 is'lthreaded. This housing, which connects With a pipe 4 leading from ay source of-air under pressure', not shown,

n is provided with a .valve seat 5, against which a valve 6 operates; the valve being `-lmounted on a stem 7 that extends from the housing Where it is engaged by one end ol a lever 8'- pivotally supported, as at y9, from the housing and to which alink .10, whereby it maybe-moved to` open the valve, is con-I 55. nected.v A spring 11,is coiled about the outer end portion of the stemand is so co'nneeted therewith that it normally holds the valve in closed position to prevent the dicharge of air into the cup 1. .Alsofentering the cup centrally through lthe opening 2 is a small pipe 12 through which oil or other liquid to be atoi'nized'n'iay be discharged into the cup. This pipe enters the side of, the valve housing into the air channel and is then turned upwardly v through the valveconneetion and opening 2 l 1,611,511 PAT/ENroFFicEg into the cup. The oil pipe is of such dianieter that it Will leave anv annular space 15 about it through which air may enter the cup. The outer end of the pipe may connect to a source of supply, not shown, which may iow by gravity, or by other pressure, and which may be controlled by a valve 16 in the pipe operable by means of a lever 17 that is connected with the link 10; the connection with the link being Such thatv movement of the link simultaneously effects the closed end opening of both the valve 6 and valve 16. l i

Fixed over the vdischargerend of the oil pipe Within the cup, is a delector plate18 located in spacedI relation fromv the end of the pipe and disposed horizontally and at :i right angle to the axle line of the pipe.' The construction described provides that upon opening the valves 6 and 16, air will be discharged into the cup through the opening 2 and oil will be discharged through the pipe 12 against the deilector plate 18 and will thereby be thrown laterally in an atomized condition and caught up/by the air and carried upwardly from the upper end of the cup.

Over the upper end of thecup isa disk 2O rotatably supported by a pin 21 fixed in a cross bar 22 across the upper end of the cup.v The disk is mounted so as to revolve in a plane that is parallel with and close to the end ofgthe cup. Itis lprovided near its center with a plurality of perforations 24 and upon its periphery' with impeller blades 25 against Which the air discharged through the cup will impinge to cause the disk to revolve at a high rate and to thereby more finely atomize the oil and causeit to be discharged upwardly and laterally vin all d irections.

In Figure 1 We have shown the atomizer' located beneath an inverted bread pan 30 on a lsupport 31 and used in this instance as I a means ofl oiling the interior of the pan before the bread is placed therein for baking.

It is to be understood, however, that such atomizers are adaptedto be used for various purposes and in various types of machines,

and We do not Wish to limit its use to any single device or machine.

Itis further apparent that details of con-y struction in the device, especially in the v means of control for the oil and air delivery, A could be varied Without /depa-rting from the rspirit of the invention and for 'this reason we do not shown. v

The matter shown and claimed herein is wishto be limited to the details described but not claimed in our Letters Patvent No. 1,522,867 issued Jan. 13, l1925. f

1 Having thus described our invention, what We claim as new therein and desire to secure by Letters-Patent, is :A

l. An atomizerv comprising a cup-dike body, a pipe entering the cup for Athe def livery ofthe liquid to be atomized, a deflector plate over the end ofsaid pipe Where- 'by the liquid is discharged-laterally thereof and a delivery pipe for air under pressure entering theJ base of the cup, and means for simultaneously controlling the iniiuX of air i 4and liquid im@ Said cup-Miike body.

the end of said. pipe against which the liquid' is discharged. x 3. An atomizer comprising a. fcup-like y body, "a delivery pipe for air under pressure leading into the base-ofthe cup, a delivery i. pipe'for the liquid to be 'atomized leading into the'cup centrally within the air delivery pipe and fa deliector plate supported in spaced relation from the end of the latter pipe against Whidh the liquid is discharged and deflected laterally'.

impeller mounted overthe open end of the cupl to be revolved by the discharge of air F` tlieieagainst.

.5. An atomizer comprising a cup-like body, a-n air` delivery pipe entering the base lof theicup, an oil delivery pipe entering the cup centrally Within the air delivery pipe, a .deflector' plate supported from the end of the oil delivery pipe, and a diskl rotatably mounted over the end of the cup adapted to be revolved by the discharge of air therethrough; said fdisk having impeller blades about its periphery and perforations through its body.

6. An atomizer comprising a cup-like body, a delivery pipe for air under pressure leading into the base of the cup, a delivery pipe for the liquid to beatomized leading into'the cup centrally Within `the air delivery pipe, a detlector `plate supported in spaced relation from the end 'of the latter pipe, an impeller rotatably mounted above the open end' of the cup, valves in the air and liquid delivery pipes and means for simultaneously opening and closinr said valves.
